HER2+ Early-Stage Breast Cancer: Peri-Operative Therapy

Author(s)Sarah Sammons, MD, Duke Cancer Institute, Julie Collins, MD, MedStar Georgetown University Hospital, Kelly McCann, MD, PhD, Ronald Reagan UCLA Medical Center

KOLs in breast cancer provide insights on de-escalation of adjuvant anti-HER2 therapy and need for HER2 testing of residual disease after neoadjuvant therapy.

Data from the following clinical trials are discussed:

Three-year follow-up of neoadjuvant chemotherapy with or without anthracyclines in the presence of dual HER2-blockade for HER2-positive breast cancer (TRAIN-2): A randomized phase III trial. (van der Voort A et al. 2020 ASCO annual meeting. Abstract 501.)
Primary analysis of KAITLIN: A phase III study of trastuzumab emtansine (T-DM1) + pertuzumab versus trastuzumab + pertuzumab + taxane, after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer. (Harbeck N et al. 2020 ASCO annual meeting. Abstract 500.)
Adjuvant trastuzumab emtansine (T-DM1) vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2+ breast cancer: Subgroup analysis from KATHERINE. (Loibl S et al. 2020 ESMO Breast Cancer annual meeting. Abstract 96O.)
